Report: Marcia Clark stumped over O.J. Simpson knife development

One of the key players in the O.J. Simpson 1995 murder trial is saying she does not know what to make of Friday's revelations that authorities are studying a knife they were told was found at the scene by a construction worker in 1998.

Like retired Judge Lance Ito and late defense attorney Johnnie Cochran, former prosecutor Marcia Clark was one of the more well-known characters in the real-life drama of Simpson's trial on charges or murdering his wife, Nicole Brown Simpson, and friend, Ron Goldman. Clark tells Entertainment Tonight that she is stumped over Friday's developments that involve the knife alleged to have been handed over to a Los Angeles traffic cop.

Authorities learned of the knife's existence last month, police said at a news conference on Friday.

"I really don't know what to think of it," Marcia Clark, now 62 and a crime author and speaker on the lecture circuit, told ET. "I can't believe someone gave a police officer what appears to be, could be, important evidence in a case -- even if it is closed -- and takes it home. I don't know what to say about that except I can't believe it, but it's apparently what happened."

"I don't know whether to say it is truly evidence," Clark said. "It might be a hoax. It might be somebody who planted it and then just pretended to find it and gave it to the off-duty police officer, you don't know."

She adds, "I"m glad the LAPD is taking it seriously and subjecting it to testing so we can find out."

If the knife did play a role in the murder, it is possible that organic evidence can still be useful, Clark told Entertainment Tonight.

"They recover DNA on mummies in Egypt," she said. "It's entirely possible that if there is some DNA to be recovered that it could be found, especially with today's technology, which is more sensitive."

She adds, however, that there is slim likelihood that any legal development will come out of the knife find.

"The likelihood of any prosecution stemming from this evidence is very, very slim," Clark says. "

Clark, contacted through a publicist, could not be reached Friday.

F. Lee Bailey, a former defense lawyer for Simpson in the case, told Fox25 television that the development was "ridiculous."

"OJ did not drop (the knife) on his property any more than he did the gloves," the news organization quoted Bailey as saying. "The whole thing is ridiculous."
